Did you know?

A polyphase quadrature filter, or PQF, is a filter bank which splits an input signal into a given number N (mostly a power of 2) of equidistant sub-bands. These sub-bands are subsampled by a factor of N, so they are critically sampled. An important application of the polyphase filters (of FIR type) concerns the filtering and decimation of large band (and so high sample rate) input signals, e.g. coming from a high rate ADC, which can not be directly processed by an FPGA or in some ca…

WebNov 15, 2011 · The Polyphase Filter Bank (PFB) is a signal-processing technique that reduces these drawbacks. In a nutshell, what a PFB spectrometer does is this: Instead of taking an N-point transform directly, a block of data of size N x P = M is read, and multiplied point-by-point with a window function (in other words, the data is 'weighted').
